Yo, was just wondering if someone could tell me if any vac lines need to be connected to the front of the inlet mani? The car had a dumpvalve on it when i got it which was attached to the front port on the intake manifold, I have since removed it temporarily and was wondering if anything needs to be connected to it ie. compressor housing... etc and if not would a vac line onto the said port straight to a boost gauge provide a reliable/accurate reading? Have had a bit of a trawl and couln't much useful info!
Many thanks!
Many thanks!
